The species in the review list always require documentation, reviewed by the seven member Records Committee, to archive the details of birds rare in Iowa. This list is subject to change annually as we learn more about distribution and as records ebb and flow. Check back after the Records Committee annual meeting, usually in October, to see those changes.
The following species, although meeting criteria to be regular in the state, should be documented when they are observed away from known locations:
Casual - recorded in 3-8 of the last 10 years.
Accidental - recorded in 0-3 of the last 10 years.
Extirpated - formerly recorded; no wild birds recorded in the state in recent years.
The Early-Late Dates are updated four times each year after each seasonal report has been published. This list is intended to give birders a guideline for providing details and perhaps documenting birds observed outside of the know time frames. These docs are reviewed by seasonal editors to substantiate changing patterns. Print a copy for your car.
Any species new to the state is automatically on the review list. The species name in this list is a link to the records that have been entered into the database.
